【摘要】 溜井是矿山运输的重要通道。在矿山开采过程中，它起着非常重要的作用。溜井一旦由于某种原因出现故障，将会影响整个矿山生产的正常进行。 本课题以黑沟三条深度分别达362m、529m和561m的高深单段垂直式溜井为研究对象，在总结国内外放矿溜井，特别是高深溜井矿石移动规律和生产经验的基础上，根据黑沟溜井工程地质勘察和溜井放矿模型试验结果，对影响溜井正常生产的因素进行研究，从溜井结构设计、生产技术与管理等方面出发，深入探讨研究了高深溜井正常生产的途径与措施。在溜井结构设计方面，对超深溜井的可行性进行了论证；对溜井下部结构形式和参数的合理确定进行了探讨研究。在溜井生产管理控制和故障处理方面，评述了溜井降段方法；对溜井磨损因素进行了分析，并提出了降低溜井磨损速度，延长溜井使用寿命的措施；对溜井的堵塞原因进行了详尽的分析，阐述了溜升堵塞的处理方法及预防措施。对指导黑沟溜井的生产实践，确保三条溜井在服务年限内安全正常生产有着重要的意义。 本课题属应用研究类型，对同类矿山溜井的设计与生产管理具有十分重要的参考价值。更多还原

【Abstract】 A chute is an important passage in transport of mine.it plays a very important role in the service time limit of mine.The chute emergents break down because of a certain reason,it will affect the normal proceeding of production of whole mine.The research objects is three high-deep perpendicular type chutes of HeiGou Iron Mine in this paper,with the depths respectively is 362 meters,529 meters and 561 meters, the factors that influences normal production of high-deep chute are analysed and researched,with the bases of the production experiences and ore moving law in high-deep chute around the world ,and the result of HeiGou Mine chute engineering geology investigation and put ore model experiment of the chute. Proceed from some aspects such as the chute construction design,production technique and management,and discusses the path and measure of the normal production of high -deep chute.In the aspect of the chute construction design, possibility of high -deep chute is argued, and reasonable certained of chute lower part construction form and parameter is researched. In the aspect of production management control and removal break down,the decline method and the wear away factors of chute are analysed, and the method of lower wear away speed, and prolong the service time limit of the chute are brough forward,the reasons, the removal methods and prevention measures of chute stoppage are analysed in detail. It is very useful in leading production practice, and insuring the safety and normal production of Heigou chutes in its service time limit.This subject belong to the application study type, and have extensive theoretical significance and practical value the same kind mine chute,especially in the chute construction design and production management.更多还原
